WOODY: Hey, listen, no one's getting replaced. This is Andy we're talking about…It doesn't matter how much we're played with. What matters is that we're here for Andy when he needs us. That's what we're made for. Right?
This is the toy mission statement right here. It's every plaything's destiny. They exist to play with kids. They need to be there for Andy no matter how they feel. It's kind of sad in a way, but sweet to know that even toys have a purpose in life.
WOODY: All right, that's enough! Look, we're all very impressed with Andy's new toy.
WOODY: T-O-Y! Toy!
BUZZ: Excuse me, I think the word you're searching for is "space ranger."
WOODY: The word I'm searching for I can't say because there's preschool toys present.
This is our first hint that Buzz is pretty clueless. He doesn't realize his true identity. He's thinks he actually a space ranger…even though everyone else knows he's just a toy. A cool toy, but still.
WOODY: You actually think you're the Buzz Lightyear? Hey, look, everybody! It's the real Buzz Lightyear!
BUZZ: You're mocking me, aren't you?
WOODY: Oh, no, no, no, no, no. Buzz look, an alien!
Woody gets a pretty big chuckle out of this. Sure, he thought Buzz was putting on an act with the whole space ranger thing, but now he realizes Buzz is 100% serious about saving the galaxy from the evil emperor Zurg. Good luck doing that from Andy's bedroom.
ANDY: Mom, have you seen Buzz?
ANDY'S MOM: He should be right in your room, where you left him? Andy, I'm heading out the door!
ANDY: Mom, I can't find him!
ANDY'S MOM: Well honey, just take some other toy. Now, come on!
This is a super sad scene (and the dialogue doesn't totally do it justice), but Woody gets to watch this whole exchange as Andy desperately looks for his missing Buzz Lightyear toy. Woody finally understands the truth—his identity has changed and he's no longer Andy's favorite toy.
WOODY: He doesn't realize I'm not there? I'm lost! I'm a lost toy!
This is another really bummer moment. Woody's feeling a lot of things here in just a few seconds. He feels betrayed by Andy—doesn't the kid realize one of his favorite toys is missing? Doesn't he care? And then Woody's identity has changed again. He's not Andy's toy anymore. He's now officially lost.
WOODY: You. Are. A. Toy! You aren't the real Buzz Lightyear! You—you're an action figure! You are a child's play thing!
BUZZ: You are a sad, strange little man, and you have my pity.
Poor Buzz. He just doesn't get it. No matter how many times Woody tries to explain to him what's going on, Buzz can't get it through his head. (The helmet probably doesn't help matters, either.)
WOODY: What happened to you?
BUZZ: One minute you're defending the whole galaxy, and, suddenly, you find yourself sucking down Darjeeling with Marie Antoinette and her little sister.
Okay, this might be even sadder. Buzz has finally—finally!—figured out the truth. Yes, he's a toy. After all, he did see a commercial for himself on TV. That's a pretty big blow to his space ranger ego. After all, he thought he was different, maybe even better, than these strange creatures in Andy's room. Turns out he's one of them after all. That's make him feel pretty small and worthless.
BUZZ: No, Woody. For the first time, I am thinking clearly. You were right all along. I'm not a space ranger. I'm just a toy. A stupid, little, insignificant toy.
WOODY: Wait a minute. Being a toy is a lot better than being a space ranger […] over there in that house is a kid who thinks you are the greatest, and it's not because you're a space ranger, pal, it's because you're a toy. You are his toy!
Who are these guys exactly? They may just be toys, but they're toys that mean a whole to one little boy. They make him happy. Could anything in the world be more important? After this little speech, Buzz finally understands who he is and what he needs to do. Hey, that's the power of monologues.
